Abstract: 1. A method of multi-protocol telecommunications routing optimization for transferring a data file to a remote destination in a telecommunications switching system comprising a plurality of interfaces, each of said interfaces interconnected with an associated telecommunications path, each of said telecommunications paths having predetermined parameters associated therewith stored in a memory in said switching system and variable parameters associated therewith, said method comprising the steps of: a) measuring said variable parameters for each of said paths; b) analyzing said measured variable parameters and said predetermined parameters; and c) determining which of said paths provides an optimal set of characteristics for transferring the file to the remote destination. 2. The method of claim 1 in which said determining step analyzes a set of programmed user priorities in determining which of said paths provides the optimal set of characteristics for transferring the file to the remote destination. 3. The method of claim 2 in which the user priorities are predefined and stored in said switching system memory. 4. The method of claim 3 in which said predefined user priorities may be changed by said user prior to said analysis step. 5. The method of claim 2 in which telecommunications path variable parameters comprises the data transfer speed of said path at a given point in time. 6. The method of claim 2 in which said telecommunications path predetermined parameters comprises the cost per unit time of utilizing said path. 7. The method of claim 6 in which said cost per unit time is a function of the current time of day. 8. The method of claim 6 in which said cost per unit time is a function of the current day of week. 9. The method of claim 1 in which said telecommunications path predetermined parameters comprises a measure of data transfer reliability of said path. 10. The method of claim 1 in which said telecommunications path predetermined parameters comprises a measure of data transfer bandwidth of said path. 11. The method of claim 2 further comprising the step of analyzing the size of the file to be sent in relation to said user priorities. 12. The method of claim 1 comprising the additional step of first ascertaining if an interface is available prior to performing said analysis. 13. The method of claim 3 in which each of said predetermined and measured parameters are weighted with respect to said user priorities in performing said analysis step. 14. A telecommunications switching system comprising: a) a first memory for holding a data file to be transferred to a remote destination; b) a plurality of interfaces coupled with said first memory, each of said interfaces interconnected with an associated telecommunications path capable of transferring the data file with the remote destination; c) a second memory for storing predetermined parameters associated with each of said telecommunications paths; d) means for measuring the value of a variable parameter associated with each of said telecommunications paths; e) processor means operatively associated with said second and third memories and said variable parameter measuring means for determining which of said plurality of telecommunications paths should be utilized for transferring the data file in accordance with said predetermined telecommunications path parameters and said measured variable parameters. 15. The system of claim 14 further comprising a third memory for storing a set of user priorities regarding the transmission of data files, and wherein said processor means determines which of said plurality of telecommunications paths should be utilized for transferring the data file in accordance with said user priorities. 16. The switching system of claim 15 further comprising input means for allowing a user to change said user priorities in said third memory. 17. The switching system of claim 15 in which said variable parameter measuring means performs a measurement of the data transfer speed of each of said telecommunications paths. 18. The switching system of claim 17 in which said data transfer speed measurement is performed by a ping test. 19. The switching system of claim 15 in which the predetermined parameters stored in said second memory comprises the cost per unit time of utilizing the telecommunications paths. 20. The switching system of claim 19 in which the cost per unit time is a function of the current time of day. 21. The switching system of claim 19 in which the cost per unit time is a function of the current day of week. 22. The switching system of claim 15 in which the predetermined parameters stored in said second memory comprises a measure of data transfer reliability of each of said paths. 23. The switching system of claim 15 in which the predetermined parameters stored in said second memory comprises a measure of data transfer bandwidth of each of said paths. 24. The switching system of claim 15 further comprising means for ascertaining if an interface is available for data file transfer.
